[RFC][PATCH 8/12] ACPI: Remove old GPE API and transition code entirely to new one

Rafael J. Wysocki
2009-11-29T15:46:23Z

From: Matthew Garrett <mjg@redhat.com>

Remove the old GPE type handling entirely, which gets rid of various quirks
like the implicit disabling with GPE type setting. This requires a small
amount of rework in order to ensure that non-wake GPEs are enabled by
default to preserve existing behaviour.
